Molecular polaritonics: modifying chemistry with quantized light
Tuesday 18 February 2025, 05:00am
Professor Oriol Vendrell, University of Heidelberg
Location : AB2-5B
About the speaker: Professor Oriol Vendrell from University of Heidelberg is the leader of the Theoretical Chemistry Group. His interests lie in molecular polaritonics, ultrafast molecular science and quantum dynamics.
Abstract: Polaritonic Chemistry has emerged in recent years as a quickly evolving field where new and exciting experimental and theoretical results appear in rapid succession. At its core is the aim of modifying, and ultimately controlling chemical processes with confined electromagnetic radiation instead of the usual approach with optical or infrared lasers (1). From a different perspective, molecules can be used to tune the properties of confined light, thus providing a handle on properties such as energy transport in materials (2). In this talk, I will introduce the key concepts behind this paradigm and will discuss the main challenges and opportunities. These will be illustrated with recent theoretical results from our group covering excited-state, non-adiabatic chemical reactions (2,3), ground-state, thermally activated chemistry (4), and excitonic-polaritonic transport (5).
